Silk O/v – Background
In 2001, NATO Networking Panel
agreed installation of Regional
Network for NISs of the Southern
Caucasus and Central Asia
Would connect existing NRENs
into GEANT
Start with own resources – $2.5 M
for 3 yrs
Allow to be extensible by others

Silk O/v – Basic Technology
VSAT Technology
DVB Shared Channel from hub
SCPC from remotes
Uses Eurasiasat strapped beam transponder
Hub in Hamburg with 5.6m dish
Remotes in 8-9 NISs, each with
2.4 or 3.8 m dishes
Routers connecting to NRENs
155 GB Content Engine
Routers and Silk NOC part of Silk Network

Silk O/v – Schematic of the Silk System
Silk O/v – Architectural Overview
Hub Earth Station at DESY accesses
European NRENs and Internet via GEANT
Provides direct International Internet access
National Earth Station at each Partner site
Operated by DESY
Provides Internet access via satellite
Additional earth stations from other sources
Routers for each Partner site
Linked on one side to the Satellite Channel
On the other side to the NREN

Status - Current Status
All original 8 sites operational
We are currently operating with 15 MHz
Currently 17.4 Mbps DVB, 4.4 Mbps transmit
The caches currently save about 10% B/w
Caches only store pages own E/s requests
Have implemented CIR quotas

Status - Governance
Have set up Silk Board (SB)
Silk Managers
Funders
One representative each Silk country
Invited Guests
Set up Silk Executive Committee (ExCo)
Silk Managers
One representative from each region
SB meets 3 x per year, mainly in Silk
countries
ExCo has 2 Teleconferences per month

Status – Co-funding
NATO has put in $2.7M
EC funds SPONGE management at $220K
DESY houses hub and runs NOC at $400K
Cisco Donation now worth $550K
ISOC donations for workshops - $120K
Have held one so far, but sent people to CEENET one
NSRC donations for books/WLAN - $50K
IREX is putting in – $30K
Soros/Eurasiasat travel - $30K
Many are funding projects that build up national
infrastructure using Silk
Soros, EC Tacsis, UNDP, World Bank

Status – Personal Communications
Have provided 2 Cisco phones per site
UCL operates voice server
UCL has put dial-out on server to very
limited outside lines
Used regularly for ExCo meetings
Have done extensive H.323 usage
Included Heads of State and NATO SecGen
Distance lectures including World Bank
Requires using CIR in both directions

Extending Silk – Possibilities
Have started talking to other funding
agencies to provide extension
Could be just extra national bandwidth
Could be extra VSATs – now adding Kabul
Could be Receive-only earth stations
Could be extra networks on Silk routers
Could be alternate activity like IPv6
Early discussions look promising
IREX and Soros will provide funds
University of Central Asia will use it via
funds from Aga Khan.
Thinking the future
Extending Silk – Workshops
Doing 6 workshops – mainly in Russian
Mainly from ISOC funds, one co-funded
ANW from NATO and CEENET
Security – Armenia, June
Wireless – Hungary, August
Distance Education - Azerbaijan, September
IPv6 - Hamburg, September
DNS, Registration, address allocation Kazakhstan, November

IPv6 Activities
Countries expressed interest in getting
experience – but not at cost of IP4 service
Fairly easy to do with dual-stack router
and tunnelled IPv6
Native IPv6 needs special hardware for DVB
ESA/IABG agreed to provide IPv6/DVB H/w
ESA providing some B/w for testing
6NET providing some B/w for dissemination
Each NIS will provide small IPv6 facilities

Longer Term – Future Steps
NATO Support should continue after 7/05
But at a reduced rate with declining funding
Co-funding is vital to many others also
Hard to achieve with these countries
Form of Connectivity will become hybrid
Satellite necessary for some locations
Fibre will come into some sites; already
looking at terrestrial possibilities
Other satellites cheaper than this Silk
solution – particularly in Caucasus

Thinking the future
Longer Term – Future Steps -2
Most terrestrial solutions go through Russia and
perhaps Kazakhstan
Will become cheaper, but acceptable politically?
EC starting specific Caucasus Programme
Perhaps Caucasus connects by fibre to GEANT, some
others stay satellite
Discussing Central Asia plans with APAN/CCIRN
Perhaps there will be links to Pacific Rim
Should use satellite broadcast capability
Both Multicast and Broadcast caching
Will make proposal to NATO Science Committee
in October, and also to EC (not only IST)
